| 摘 要： | 大地电磁测深因成本低、勘探深度大而获得地球物理工作者的青睐,同时其不受高阻层屏蔽并对高阻层下的低阻层有较好的反映,这些优势使得MT在地热资源探测的应用中变得越来越重要。本文通过对测区的5条MT剖面资料的精细反演并结合该地区的地质及重磁资料对处于火成岩背景条件下的水热型地热资源进行勘查。以岩石物性为基础,通过地质资料分析和MT层状介质连续反演、重力-电法综合解释进一步了解该地区地质特征,结合该地区已有的地热资源和MT资料研究成果对有利勘探区进行评价。

| Abstract: | Magnetotelluric sounding(MT) gets the favour of geophysical workers because of low cost and great exploration depth.Meanwhile,it can not be shielded by the high resistance layer and reflect well on the low resistance layer under the high resistance layer.Therefore,MT becomes more important in geothermal resources exploration.According to fine inversion of the measured data of 5 MT profiles and gravity and magnetic data in this region,this paper detects geothermal resources of hydrothermal type under the con... |
